Question 1 of 1
1. Question
The nurse is preparing to suction a client via a tracheostomy tube. The nurse should plan to limit the suctioning time to a maximum of which time period?
Correct
Answer: Option 2 is correct answer.
Rationale: Hypoxemia can be caused by prolonged suctioning, which stimulates the pacemaker cells in the heart. A vasovagal response may occur, causing bradycardia. The nurse must preoxygenate the client before suctioning and limit the suctioning pass to 10 seconds. Test-Taking Strategy: Focus on the subject, the procedure for suctioning. Recall that during suctioning, the client’s airway is blocked; therefore, you should be able to eliminate options 3 and 4 easily. From the remaining options, eliminate option 1 because of the short time frame. Five seconds does not seem reasonable to achieve removal of secretions.

Comparing Tracheostomy tubes
Tracheostomy tubes are made of plastic or metal and come in uncuffed, cuffed, or fenestrated varieties. Tube selection depends on the patient’s condition and the doctor’s preference. Make sure you’re familiar with the advantages and disadvantages of these commonly used tracheostomy tubes.
Tracheotomy
A tracheotomy provides an airway for an intubated patient
who needs prolonged mechanical ventilation and helps remove lower
tracheobronchial secretions in a patient who can’t clear them. It’s also
performed in emergencies when endotracheal (ET) intubation isn’t possible, to
prevent an unconscious or paralyzed patient from aspirating food or secretions,
and to bypass upper airway obstruction due to trauma, burns, epiglottiditis, or
a tumor. After the doctor creates the surgical opening, he inserts a tracheostomy
tube to permit access to the airway. He may select from several tube styles,
depending on the patient’s condition.
